Infection of plants with pathogens like viruses or fungi often leads to a response of the host
ranging from very mild to very severe. A very mild response usually does not result in …

Pathogenesis-related proteins (PRs) are induced in tobacco and other plant species by both
biotic and abiotic agents, comprising necrotizing and non-necrotizing viruses, viroids, fungi, …

Plant defenses against pathogens and insects are regulated differentially by cross-communicating
signaling pathways in which salicylic acid (SA), jasmonic acid (JA), and ethylene (ET) …

In several plant species, upon infection with viruses, vi~ oids, fungi or bacteria the development
of symptoms is accomparAed by the appearance of one or more new proteins. Such …

Salicylic acid (SA), jasmonic acid (JA), and ethylene (ET) are each involved in the regulation
of basal resistance against different pathogens. These three signals play important roles in …

A procedure is described for purifying the b 1 , b 2 and b 3 proteins from leaves of Nicotiana
tabacum cv. Xanthi-nc, a cultivar reacting hypersensitively to tobacco mosaic virus (TMV). All …

Plants develop an enhanced defensive capacity against a broad spectrum of plant pathogens
after colonization of the roots by selected strains of nonpathogenic biocontrol bacteria. In …

Plants are exposed to very different attackers, including microbial pathogens and herbivorous
insects. To protect themselves, plants have evolved defensive strategies to counteract …

Systemically induced resistance is a promising strategy to control plant diseases, as it affects
numerous pathogens. However, since induced resistance reduces one or both growth and …

The induction of a hypersensitive reaction in ‘Samsun NN’ tobacco by tobacco mosaic virus (TMV)
at 20C leads to the development of both localized and systemic acquired resistance, …
